South Polar Ice – NASA's Mars Exploration Program


Context image
Today s VIS image shows a portion of the south polar cap. The visible layers were created over millennia by deposition of winter ice and summer dust. This image was collected at the end of the southern summer season.
Orbit Number: 84988 Latitude: -86.0994 Longitude: 144.46 Instrument: VIS Captured: 2021-02-10 04:50

NASA s Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA s Science Mission Directorate, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from J ....

Planetary scientist receives NASA's Early Career Award

NASA has selected Northern Arizona University assistant research professor Alicia Rutledge as one of only five early-career scientists in the country to receive funding through its Planetary Science Early Career Award program, which supports outstanding early-career individuals.
Rutledge s proposal, Ice, Ice, Rock: Analog Studies in Cold Environments to Understand Past Climate, outlined how the award would enable her to invest in a portable laboratory that she could use to better conduct her research. ....

"Mountain of Mystery" -- Mars' Mount Sharp at Gale Crater


 
 
“To me, Mars is the uncanny valley of Earth,” said planetary geophysicist Kevin Lewis of Johns Hopkins University. “It’s similar but was shaped by different processes. It feels so unnatural to our terrestrial experience.”
In a 2019 paper in Science, NASA researchers detail how they repurposed sensors used to drive the Curiosity rover and turned them into gravimeters, which measure changes in gravitational pull. That enabled them to measure the subtle tug from rock layers on lower Mount Sharp, which rises 3 miles (5 kilometers) from the base of Gale Crater and which Curiosity has been climbing since 2014. The results? It turns out the density of those rock layers is much lower than expected. ....
